Abstract (en)
[origin: EP2858401A1] Embodiments of the present invention relate to the technical field of wireless communications, and in particular, to a method, system, and device for configuring channel measurement and DL CSI feedback, so as to implement measurement in a dynamic TDD system. The method for configuring channel measurement according to the embodiment of the present invention comprises: a network side device dividing downlink subframes into multiple downlink subframe groups according to an interference condition on the downlink subframes; and the network side device notifying a user equipment of channel measurement configuration information corresponding to the downlink subframe groups. The network side device notifies the user equipment of the channel measurement configuration information corresponding to the multiple downlink subframe groups that are obtained according to the interference condition on the downlink subframe, thereby implementing measurement in the dynamic TDD system.
